6bea810c23 enable dot_init.h on both sparc & sparc64, fixing .init & .fini processing 
for both platforms.  they share dot_init.h with a single #ifdef #define
difference...

2d62241cb9 Reorganization of crtbegin/crtend. 
o  Primary mod: alpha and i386 code for .init and .fini section fallthroughs
o  Actual fallthru is not yet enabled, see csu/{alpha,i386_elf}/Makefile
o  When enabled, should fix bin/12865 & should fix at least one WINE bug,
   see http://www.winehq.com/hypermail/wine-devel/2001/05/0021.html
o  Also, removed the function pointer hack put in to prevent gcc from
   incorrectly attempting to do short calls over section boundaries,
   on some architectures, rather, simply simply move ctors() and dtors()
   into .init and .fini.
Other notes.
o  Our crtbegin.c and crtend.c were completely in C, despite
   the fact that .init and .fini section fallthroughs require machine code.
   These modules implement the gnu ctors/dtors mechanism directly, eliminating
   in part the need for the elf .init/.fini section fallthrough. However,
   if we ever want to use the gnu-provided constructor support, we need to
   do the fallthrough, at least one program (WINE) apparently uses the
   feature independently, and other compilers may depend on the mechanism.
o  It is amusing that the previous NetBSD _init() and _fini() were put
   into the .init and .fini sections, because nothing is gained over
   plain .text if they don't fall through. Cargo cult!
o  Other elf ports will need to copy the alpha and i386 example mods.

0113cca535 Our ARM ELF ld(1) currently has problems with PIC relocations, so don't 
generate them.  I suspect this is safe until we get PIC in general working.

94581370f5 The ELF ABI declares that argc must fill an `argument slot'. Make it so. 
For __sparc_v9__ only, do a hack to make executables work temporarily before
and after the kernel is switched.

d71ca2d66e __syscall takes a quad_t as its first argument, not an int. 
_strrchr takes an int (due to promotion) as its third arg.
don't print the null byte at the end of string.
error messages should end with a linefeed.

fe5a2bf74b remove the `static'' from static void __start()' and `static void ___start()' 
because an overly aggressive gcc -O3 "cleverly" optimizes the functions out.
noted in [port-i386/8493], but seen in other ports as well.
